Which of the following is not attached to the central carbon atom in an amino acid?

Biology

dangina [55]3 years ago
3 0

<u>Answer:</u>

<em>An oxygen is not attached to the central carbon atom in an amino acid.</em>

<u>Explanation:</u>

To understand this, we need to look at the <em>simple molecular structure of amino acids.</em> The basic structure of amino acid consists of an amine (NH_2), a carboxyl (COOH) functional groups.

There is also a R-Group for a particular amino acid on the side chain of it. Although oxygen is one of the key constituents of amino acid it is not directly attached with the <em>central carbon atom in an amino acid.</em>

Read the following scenarios carefully and explain how natural selection will occur in each.
IrinaK [193]

Answer:

The correct answer is - Noctural worms have the advantage over diurnal due to the fact that the nocturnal worms are burrowing during the feeding time of birds.

Explanation:

Natural selection is the process in which organisms adapt according to environmental changes to increase their survival rate. Natural selection leads to natural changes in different organisms.

In this case, diurnal worms are forced by the natural selection here to adapt to the change if they want to survive. Here, natural selection works for the nocturnal and against the diurnal.

what is the meaning of phosphoryl transfer potential and what does it mean to have a high or low phosphoryl transfer potential?
makvit [3.9K]

Phosphoryl-transfer potential is the ability of an organic molecule to transfer its terminal phosphoryl group to water which is an acceptor molecule. It is the “standard free energy of hydrolysis”.

Explanation:

This potential plays a key role during cellular energy transformation by energy coupling during ATP hydrolysis.  

A compound with a high phosphoryl-transfer potential has the increased ability to couple the carbon oxidation with ATP synthesis and can accelerate cellular energy transformation.  

A compound with a high phosphoryl-transfer potential can readily donate its terminal phosphate group; whereas, a compound with a low has a lesser ability to donate its phosphate group.

ATP molecules have a high phosphoryl transfer potential due to its structure, resonance stabilization, high entropy, electrostatic repulsion and stabilization by hydration. Compounds like creatine phosphate, phosphoenolpyruvate also have high phosphoryl-transfer potential.
